Today, Microsoft has provided us with more detail about why existing headsets are currently incompatible. There's also hope that existing devices may end up working after all (with help).

"The Wireless Controller has been redesigned to allow for higher data transfer speed between the controller and the console," a Microsoft representative told us. "This also required creating a new expansion port design for headsets and future controller add-on devices which is different from a standard audio plug input. Xbox plans to develop solutions in the near future to allow consumers to connect many brands of wired gaming headsets to the Wireless Controller for gaming and chat audio.”

That last part should make consumers very happy, especially if they've already invested hundreds in a premium personal audio solution. In short: there is hope, audiophiles.
